Start Your Engines!, 2 oz, 8-Pack | Revitalizes fuel systems to help start non-running 2- and 4-cycle engines.

After fighting with my 2 year old Craftsman lawn for months, trying to pull start it with over 50 try’s every week. I started to use a small amount of this spay in the gas and in the intake. It now starts first try every time. Just amazing stuff!

I recommend this product for engines that will in fact start but not run well. I highly recommend it for that specific purpose, which it is designed for. It cleans the inner workings of the carburetor. Of course, you will have a cleaner carburetor if you take it apart and clean it with proper tools and a proper carburetor cleaner.You spray it in the gas tank, start the engine, and let it run a bit. It will not start an engine with a totally plugged up carburetor. Nothing is going to do that. Nor is it a fuel stabilizer, as one previous reviewer seemed to think. Nor is it a product to be used to bring life back to stale gasoline, as another reviewer seemed to think. The only thing to do with stale gasoline is drain it out and pitch it. Nor is it a product to be used for cleaning a carburetor you have taken apart to clean. You should use a proper carburetor cleaner for that purpose.I've given it four stars because it cleans out mildly plugged up carbs. It is not a miracle solution for really neglected carbs as the name suggests.

I have a 20+ year old John Deere push behind lawn mower. I have had a lot of problems starting my mower even after it came back from being serviced this mowing season. So, I thought I'd give this product a try after reading the reviews for STA-BIL. Well, the product was delivered almost a week early (Thanks Amazon!!), so I went right out to see if it helped to start my mower. I unscrewed the air filter cover and gave the carburetor intake a fast squirt with STA-BIL. Then re-attracted the air filter cover and pulled the cord...nothing...I pulled the cord a 2nd time and the mower started right up!!! I have mowed my lawn twice since then and with a little squirt with STA-BIL it starts on the 2nd pull every time!! No need for a new mower...I couldn't be happier!!

It worked great in getting a lawn mower started that had not been ran in several months

Works

Small can for the price

So after I tried two other starting fluids--both of which worked in the past--on my Kawasaki FS48, I figured I'd give Start! a try. "Fixes Non-Running Engines" huh? Pretty bold claim. So I squirted a bunch of the stuff into the year-old gas (which had been treated with Sta-Bil...ahem), and a good blast in the intake air filter. BINGO! There's an engine I won't have to tear down. I'm gonna make sure I never run out of this stuff.

Great purchase works as stared

2008 Yamaha BWS 50 CC SCOOTER IN STORAGE FOR 3 YEARS with old fuel. Would not start. Drained old fuel 90% and replaced with premium fuel. Would not start because of remaining old fuel in carburetor. Added Start Your Engines and waited 45 min. Turned over would not start. Let the fuel system revitalizer make its way to the carb and 4 hours later and 6 attempts the scooter started flawlessly and now purrs like a kitten. Highly recommended. THIS PRODUCT WORKS !!!!! DO PURCHASE.

Very good. After I sprayed it into lawn mower, it works right away. Great! Save my day.
